Downward - but the sealant will band-aid the problem if the gap is bigger at the bottom than the top (i.e. the angle of the manifold face does not match the angle of the head intake face). As already pointed out here, I need to take everything off and use feeler gauges to see where it's not mating properly.

Filing the intake bolt holes is not the right way to fit the intake.


Yeah, no [censored] Sherlock wink but I don't have a Bridgeport mill handy, nor a nearby automotive machine shop I can trust! And I wanted to get the car running again while the weather is nice and cruise-ins are frequent shruggy
